Infrafone Facts • Infrafone increase the efficiency, availability and lifetime
of industrial boilers through infrasound soot cleaning technology
• 1000 installations (900 marine installations) world wide • 65 WtE & Bio fueled boilers in Scandinavia • 9 Coal fired boilers in Germany and USA • ISO9001 certification • Headquarters in Stockholm, Sweden • Founded 1978
Infrafone History
The path towards unique knowledge
First installation: Hyltebruk, Sweden Paper mill, MgO boiler
1982 1984
First marine installation: M/S Rimula Steam boiler
Collaboration with ABB Sales focus on marine industry, steam boiler vessels
1982-1995 1995
Development of the first sound calculation program
First installation on W-t-E plant: Asahikawa and Obihiro, Japan Air Preheater and Economizer
New mechanical design: higher mechanical reliability and operation with compressed air. 1995
2001
2004 W-t-E plants: 4 installations Biofuel plants: 6 installations
New Paradigma: • High accuracy in the sound calculation program • High mechanical reliability • More acoustic power
2005
W-t-E: 30 boilers Biofuel: 35 boilers Coal: 9 boilers
2013
70’s
Infrasound, a physical phenomenon, which applications?
Infrafone Technology: Applications
Economizer
SCR Air pre-heater
ESP Ducts
500 °C > T > 140 °C Only cleaning method needed below
~260 °C
How does it work?
Sound creates oscillations in the flue gas
Increased turbulence in the flue gas
Formation of deposits is prevented.
Infrafone Technology
• Our expertise and knowledge, the key to success
Acoustic modelling software
INPUT OUTPUT
• Dimensional and operational parameters of the boiler
• Acoustic power output • Frequency • Location
• Modelling of the boiler • Modelling of the infrasound behaviour in the boiler

Infrafone Value Proposition
Reduced operational & maintenance costs – Savings on operation of steam soot blowing and
shot cleaning – The saved steam can be used for increased
production – Savings on replacement of tubes thru extended life
time
Stable ΔP, which means: – Less outages, higher energy production – Less outages, more burned waste
Lower risk for high flue gas velocity in local areas
– Savings on replacement of tubes thru extended life tube time
Sweden Mora, 8 MW Commissioning 2010 Infrasound cleaner: APM150 Cleaning area: Vertical downstream
economiser Fuel: Industrial/Household waste Performance: • The boiler has been in operation since
early 2011 without any manual cleaning of the economiser.
• The Δp is still low and stable. • The differential temperature is still high and
stable. • No other soot cleaning equipment installed.
Boiler 1, 2 & 3 Renova, Gothenburg 56 MW
Commissioning 2011 & 2011 Infrasound cleaner: APX2000 Cleaning area: External fin-tube economiser Fuel: Industrial/Household waste Performance: • Has eliminated the need for shot cleaning. • Differential pressure on a stable level. • Cleaner working environment
Sweden
Boiler 1 & 2 SYSAV, Malmö, 29 MW Commissioning 2008 & 2009 Infrasound cleaner: 2 x APL1000, 2xAPX2000 Cleaning area: Vertical downstream evaporator
and economiser Fuel: Industrial/domestic waste Performance evaporator: • Shot cleaning of the economiser has been turned off. • Lower and more stable Δp over the economiser than with shot cleaning. • The exhaust gas outlet temperature from the evaporator is lower and
stable. • The soot deposits in the high temperature area (flue gas temp 680 oC –
600 oC) of the evaporator is softer and takes longer time to build up.

Sweden P14, Norrköping, 75 MW Commissioning 2006, upgraded 2013 Infrasound cleaner: APX5000 2006-2012 APX7000 2013- Cleaning area: Vertical downstream
economiser Fuel: Industrial/Household waste Performance: • Steam soot blowing reduced from 3-4 times/day
to 1 time/week. • The differential pressure is now on a lower level
than with steam soot blowing running 3 times/day.
Norsaverket, Köping, 12 MW Commissioning 2009 Infrasound cleaner: 3 x APM150 Cleaning area: Vertical downstream
evaporator and 2 x eco Fuel: Industrial/Household waste Performance evaporator: • Steam soot blowing eliminated for all but the first tube bundle • Δp is lower than with steam soot blowing 3 times/day. Performance economiser: • With the previously installed air cleaning lances flue gas temp increased rapidly. • With infrasound technology installed, air cleaning lances were turned off and the Δp
and temperature are now on a stable low level the full season.
